자동화 네트워크 침입 탐지 시스템

초록

For the industrial network, various fieldbus protocols including Modbus/TCP are used to control the manufacturing system. To protect this idustrial network against malicious intrusion, it is important to use Network Intrusion Detection System(NIDS) because the protocol barely contains secure or cryptographic features. The commonly used NIDS are software-based and don’t guarantee real-time detection since they are not for critical industrial system. In this paper, a FPGA-based automated NIDS is proposed which can detect suspicious network packet in real-time in order to be used in industrial system.
